Here’s the latest controversial report which suggests vitamin D has no beneficial effect in reduction of fractures except for those with high risk. The report is a meta-analysis of 81 clinical trials so it’s pretty robust!
The Department of Health suggests we should take vitamin D though the Winter (Oct-Mar), and here’s the thing – ideally we should be able to make vitamin D from the sunshine, and top it up with food sources (oily fish, egg yolks). But is that enough? If your work is inside you may not see the sun, the UVB rays also don’t penetrate through sunscreen, clothing, or make-up. We know vitamin D is important to transport calcium into bones for improved bone health. Here’s an interesting overview of vitamin D.
Certainly most of the modules I study as part of my MSc Nutritional Medicine contain much content about the benefits of vitamin D, and school is still out on the other benefits it may bring apart from bone health. I think it would be wise to continue supplementing through the Winter at Government recommended daily amounts until we have further clarity.
